* The DC stages on the PBx-11 are not independent; they follow the settings of the AC stages.
Use the variable AC stages for controlling variable speed fans, heat mats, or lamps. Use the variable
DC stages for controlling variable frequency drives (VFDs).
Use relays for single-stage heating or cooling, timed events for lighting, or duty cycles for misting.
Power Block relays can control anything at your site that needs to switch ON or OFF based on
temperature, time, or duration.
Previous generation Power Blocks, PB-1 to PB-6, are no longer manufactured, but
Select Ventilation does work with them.
Customizable reports and information display
Ventilation Temperature Reports display detailed ambient and set point temperature history.
Ventilation Status Reports display a mixed graphical and textual “information snapshot” of the
selected Power Block. The report includes a one-week temperature summary and current
configuration and settings.
Ventilation Settings History Reports are similar to Ventilation Status Reports, but do not include
the temperature summary. Settings History Reports also allow you to display historical
configuration and settings.
PBx Relay Runtime Reports display the amount of time, in hours: minutes: seconds, each relay
was on.
Power Block status viewer displays the status of a Power Block's variable and relay stages. The
status viewer is an important monitoring tool you should check regularly.
